The specific embodiment
The inventor according to the theory of the relevant melancholia of the traditional Chinese medical science, has been surprised to find that the Chinese medicine composition of a kind of energy dispersing the stagnated live-QI to relieve the stagnation of QI, spleen-benefiting mind-tranquilizing through extensive and deep research.Specifically, Radix Bupleuri dispersing the stagnated live-QI to relieve the stagnation of QI in the compositions is monarch drug; Rhizoma Cyperi, Pericarpium Citri Reticulatae Viride, Cortex Albiziae, Radix Curcumae, Rhizoma Acori Graminei, Poria, Fructus Amomi, the Radix Astragali are ministerial drug altogether, wherein Rhizoma Cyperi, Pericarpium Citri Reticulatae Viride, Cortex Albiziae are regulated the flow of vital energy and middle relieving distension, the pain relieving of Radix Curcumae resolving depression promoting flow of QI and blood, Rhizoma Acori Graminei have one's ideas straightened out eliminating phlegm removing dampness appetizing, refreshment Fructus Alpiniae Oxyphyllae, Poria, Fructus Amomi invigorating the spleen for eliminating dampness, regulating qi-flowing for harmonizing stomach, Radix Astragali invigorating the spleen and benefiting QI yang invigorating; The Radix Paeoniae Alba, Semen Ziziphi Spinosae are using corrigent, change cloudy, nourishing the liver blood and tranquilizing mind.Clinical research shows that this is a scientific and effective prescription.
Depressive state is common in depression (unipolar depression), depressive neurosis, anxiety neurosis and the reactive depression etc. of affective disorders.The melancholia that the traditional Chinese medical science is alleged, be equivalent to the depressive states that disease occurred such as the depressive state of depressive neurosis, anxiety neurosis, affective psychosis of modern medicine indication and masked depression, menopausal depression, neurosis, mostly being psychogenic disorder, is the pathological changes that brain ergasia obstacle is caused.
Melancholia is because feelings will is not relaxed the caused class disease of depression and stagnation of QI.Mainly show as and feel depressed, irritable emotion, distending pain over the hypochondrium, or irritability is kind cries, and block various complicated symptoms such as insomnia if any foreign body in the pharynx.Its normal manner is lost in feelings will fluctuation, depression and stagnation of QI then, and with the passing of time the stagnation of QI does not heal, and by gas and blood, becomes and gives birth to multiterminal, can cause multiple symptom, so saying of " six kinds of stagnation-syndromes " arranged.Being six kinds of the stagnation of QI, blood stagnation, phlegm stagnancy, damp-stagnancy, heat stagnation, food stagnancy etc., wherein is earlier with the stagnation of QI, all strongly fragrant could formation such as then wet, expectorant, heat, blood, food.
The generation of melancholia is because feelings will is hindered, and depression of liver-QI causes due to the five internal organs mechanism of qi discord gradually.But mainly being that liver, spleen, the heart three are dirty gets involved and disorder of QI and blood forms:
(1) disgruntled not smooth, make liver lose bar and reach, gas loses catharsis, and causes depression of liver-QI.The stagnation of QI with the passing of time can fire-transformation, and the stagnation of QI can cause blood stasis not all right again.If stagnation of liver-QI and spleen, or ponder over puzzledly, overstrain impairing the spleen all can make dysfunction of the spleen in transportation, accumulates humidogene expectorant, causes stagnation of QI phlegm stagnancy.If turbid damp stops, or dyspepsia do not disappear, or the phlegm-damp heat-transformation, then can develop into cards such as damp-stagnancy, food stagnancy, heat stagnation.
(2) feelings will is unsuccessful, and stagnation of liver-QI presses down spleen, consumes sad gas, and nutrient blood gradually consumes, and the heart is become homeless foster, the god Tibetan of becoming homeless, and promptly so-called melancholy is overtaxed one's nerves, and can cause irritability.If chronic depression impairing the spleen, diet reduces, biochemical weary source, and insufficiency of vital energy and blood then, deficiency of both the heart and spleen, the easy impairment of YIN blood of strongly fragrant fire-transformation of a specified duration involves in kidney, hyperactivity of fire caused by deficiency of YIN, development can become all deficient times thus.
Melancholia because of disgruntled, ponder over, institute grieved, worried seven emotions hinders, and causes the liver failing to maintain the normal flow of QI, spleen mistake fortuneization, the mind is not normal, the internal organs yin and yang qi and blood disorder forms.The first cause of disease stagnation of QI and hold damp-phlegm, food stagnation, heat stagnation person under the arm, then how true card; Prolonged illness is by gas and blood, and Sthenia is transforming into asthenia, overtaxes one's nerves as for a long time strongly fragrant, and heart spleen all loses, and hyperactivity of fire caused by deficiency of YIN etc. all belong to deficiency syndrome.
Therefore, dredge mechanism of qi in early days, his disease takes place for the development that prevents the state of an illness, significant.Radix Bupleuri bitter in the mouth suffering in the pharmaceutical composition provided by the invention, be slightly cold, go into liver, gallbladder, pericardium tri-jiao channel, the effect of dispersing the stagnated live-QI to relieve the stagnation of QI, elevate a turnable ladder yang-energy is arranged, Radix Bupleuri can also improve brain blood circulation, strengthens cranial nerve nutrition; The stagnation of liver-QI spleen is considered reciprocal causation, and the Radix Astragali in the present composition, Poria, Semen Ziziphi Spinosae add Pericarpium Citri Reticulatae Viride, Cortex Albiziae, Rhizoma Acori Graminei, Radix Curcumae, Fructus Amomi invigorating spleen and nourishing heart, sedative action.In general, compositions energy soothing liver and strengthening spleen provided by the invention, resolving stagnation for tranquilization.
